b63c979fc9 meson: remove automake specific directives
EXTRA_DIST is not relevant because meson makes a git copy when creating
dist archive so everything tracked by git is part of dist tarball.

The remaining ones are not converted to meson files as they are
automatically tracked by meson.

bb8ccb050d conf: add control over COW for storage pool directories
The storage pool code now attempts to disable COW by default on btrfs,
but management applications may wish to override this behaviour. Thus we
introduce a concept of storage pool features:

  <features>
    <cow state='yes|no'/>
  </features>

If the <cow> feature policy is set, it will be enforced. It will always
return an hard error if COW cannot be explicitly set or unset.

d3aa28925f Add a check attribute on the mac address element
This is only used in the ESX driver where, when set to "no", it will
ignore all the checks libvirt does about the origin of the MAC address
(whether or not it's in a VMWare OUI) and forward the original one to
the ESX server telling it not to check it either.

This allows keeping a deterministic MAC address which can be useful for
licensed software which might dislike changes.

062f233b17 docs: drop %.png: %.fig rule
convert bin is part of ImageMagick package and uses uniconvertor to
create png file from fig files.

Unfortunately uniconvertor is python2 only and not available in most
recent distributions which makes the convert command fail with:

sh: uniconvertor: command not found
/usr/bin/mv: cannot stat '/tmp/magick-1397138DRT8Pzx4Qmoc.svg': No such file or directory
convert: delegate failed `'uniconvertor' '%i' '%o.svg'; /usr/bin/mv '%o.svg' '%o'' @ error/delegate.c/InvokeDelegate/1958.
convert: unable to open file `/tmp/magick-1397138S8ARueJXLXkc': No such file or directory @ error/constitute.c/ReadImage/605.
convert: no images defined `docs/migration-managed-direct.png' @ error/convert.c/ConvertImageCommand/3226.

It looks like that there are plans to somehow port uniconvertor into
python3 but as part of different project color-picker but the job is
far from complete.

7e5b993d3b backup: Allow configuring incremental backup per-disk individually
The semantics of the backup operation don't strictly require that all
disks being backed up are part of the same incremental part (when a disk
was checkpointed/backed up separately or in a different VM), or even
they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).

In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.

This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.

Note that no changes to the qemu driver are necessary to take advantage
of this as we already obey the per-disk 'incremental' field.
